Prepping affects the reliability of the results of the individual prepped test taker, no one else. The score reflects a false result because it is no longer measuring what it is meant to gauge. It is giving an impression of the test taker that is not true.
I don't know what Breaking Bad is, I assume a television show, but we don't watch that much TV at my house.
Not really. If prepped test takers get a higher score, this will bring them higher in the percentiles, which means that non-prepped test takers will go lower, which really means that the reliability of all scores is affected. Simple statistics.
Will students who read widely, write frequently and practise problem solving and mathematics frequently improve their scores and percentiles on the CogAT? Do these prepping activities improve scores in a material way?

"Prepping/Scamming the Cogat" = the practice of showing children ability test question types that the children are not supposed to see until the day of the test.
CoGAT test prep consists of courses or books that involve practicing over and over again the types of questions that a child can expect to see on the CoGAT.
"Hard work, study and preparation" have nothing to do with this test. The company even says that the scores are not reliable if a child takes it twice within a certain length of time: that is because a child will get a higher score simply because of familiarity with the test format. Just think how unreliable the score is if the child has been doing the questions over and over again for months.
It comes down to, do I want to sacrifice my DC for the sake of the test's reliability over 13,000 takers, 95 percent of whom will fall below the cutoff. Not interested, looking out for number one. Sorry to the purists. Seen too many episodes of Breaking Bad I guess.
